Key result
A higher sodium-to-potassium ratio was associated with increased hypertension risk (OR 1.40; 95% CI 1.01-1.94), while higher potassium intake was associated with lower risk (OR 0.51).
Why the study?
Does higher sodium and lower potassium intake increase blood pressure and the risk of hypertension in Chinese adults?
Cross-Sectional (n=2,281)
Yes
Does higher sodium and lower potassium intake increase blood pressure and the risk of hypertension in Chinese adults?
Odds Ratio: 1.4 (95% CI 1.01–1.94)
Higher sodium and lower potassium intakes, accurately estimated via two 24-hour urine samples, are significantly associated with elevated blood pressure and increased hypertension risk in Chinese adults.

Hypothesis-generating for sodium-potassium targets in Chinese adults; prospective trials needed before practice change.
Xu et al. (2017) conducted a cross-sectional in Hypertension (n=2,281). 24-hour sodium and potassium intakes vs. Lowest quintile of intake was evaluated on Risk of hypertension (highest vs lowest quintile of sodium-to-potassium ratio) (OR 1.40, 95% CI 1.01-1.94). A higher sodium-to-potassium ratio was associated with increased hypertension risk (OR 1.40; 95% CI 1.01-1.94), while higher potassium intake was associated with lower risk (OR 0.51).
